43. ssm For the normal force in Figure 5.19 to have the same magni- tude at all points on the vertical track, the stunt driver must adjust the speed to be different at different points. Suppose, for example, that the track has a radius of 3.0 m and that the driver goes past point 1 at the bottom with a speed of 15 m/s. What speed must she have at point 3, so that the normal force at the top has the same magnitude as it did at the bottom?

3. A physics student takes a scale onto the roller coaster, places it on the seat and sits on it and takes a ride. The scale reads her weight, 600 N when she is at rest. While going around the loop of radius R = 7.5 m, she looks down and sees that the scale reads 300 N as she passes through the top of the loop (at A). В A. How fast is she traveling at that instant in time?

1.Circular Motion: Your evil cousin Throckmorton has come to visit for the weekend. His favourite pastime is skateboarding. You observe him skateboard from rest down a curved, frictionless ramp. If we treat Throckmorton and his skateboard as a particle, he moves through a quarter circle with radius 3.00m. Throcky and his skateboard have a mass 25.0kg. (a) Find his speed at the bottom of the ramp.(b) Find the normal force that acts on him at the bottom of the curve.
A new roller coaster contains a loop-the-loop in which the car and rider are completely upside down. If the radius of the loop is 16.4 m, with what minimum speed must the car traverse the loop so that the rider does not fall out while upside down at the top? Assume the rider is not strapped to the car. orrect Answer O 12.7 m/s 14.0 m/s 10.1 m/s 14.9 m/s EPIC GARES II
